Hi,

I have been fiddling with 3DMax 9 for a couple of days now, and have been trying to map a texture onto a cylinder (actually a part of a missile for a flight sim).

What I do is:
1) Create a cylinder 3m long and 0,12m in diameter
2) Add the mesh select modifier, since I want to texture map the caps separately.
3) Select all the faces except the ends.
4) UVW Mapping, cylindrical type and the "Fit" so that the gizmo is correctly sized and aligned.
5) If I export this to a 3DS model, and use LithUnwrap to create a template .BMP for the texture, I find that the map exceeds the "frame", so the created .BMP does not cover the whole cylinder (I also need more space on the .BMP in order to texture the fins, etc.)
6) I do an Unwrap UVW to scale the cylinder's projection down.

The problem is that if I draw something on the texture (text, a circle,etc.) it appears really stretched on the longitudinal direction. How can I solve this?

Thanks!

Try unticking the "normalize" box on the uvw unwrap.

Uvw map should be sufficient for mapping something like this. make a map in photoshop that tiles at the edges and adjust the uvw modifier gizmo until it looks right.

The problem is I that I need to use only one image file to have all the maps that the model uses.

I've resized the unwrapped UVW by hand until it had almost the right proportions (width approx the perimeter, height the cylinder length) but this is most imprecise and still had to tweak the map features so that things like screws looked round instead of oval.

Since it should be easy for 3DS to create an UVW map with the right proportions, I was wondering....

I think the problem would come back to your uvw map modifier not being quite right. What happens when you turn off all modifiers but the uvw map and apply a checker map with 5*5 tiling? Does it look stretched?

Yes, it does appear stretched, but I think that by skipping the UVW Mapping and directly doing an Unwrap UVW selecting the vertex of the cylinder (but not those belonging only to the caps) and unchecking the normalize option will do the trick.

I managed thus to get an UVW map that looks like it has the right proportions, but I didn't have the time to explore this in detail (export to a BMP, texture it, import the image back as a material and check whether it looks right).
